TALLMAN, OF GUNNIsON, COLORADO Y l i GRAPHIC CHART Applieaiqa mea 'February 14,1928. serial No. 254,271. j

This invention relates to graphic charts of the type shown and described `in `my application for Patent No. 210,084 filed lAugust 2, 1927, patented May 21,1929, vnumber 1,713,811, of which the present application is a continuation. j

The chart disclosed in the original application comprises a face member and a back member fastened one upon the other.` The face of theback member ,is colored distinctively with respect to the surface of the face member so that when parts of the face member are removed'the exposed portions of the back member will stand out in contrasting prominence.

The face member has Aremovable strips formed between perforated or otherwise weakened lines and spaces are provided at the ends of these strips or at the endsV of the divisions on the face member in which'the strips are formed, for insertion ofthe names of subjects, individuals, teams, shifts and the like.v Y A The face member is graduated and in the use of the chart, the strips are torn away to designate degrees ofprogress by the exposed portions of thecontrasting vfacel of the background.

It has been stated in'l the (first application that the two members arefastened together, exclusive of thestrips of the 'face member,

Aby means of a suitable adhesive raudit isan object of the present' invention to provide diderent fastening means that have been The fastening means'referred vto are ofa solid character and mechanically applied, sewing, 'stitching' Vor stapling byfmeansv of thread or wirerbeing preferred; j

Another object of the invention is to prorticularly suited "for the purvide in a chart ofthe "above described type,

removable and renewable vmeansfor inserting the names of subjects or'personsoppos'ite strips are-formed; y

A further object is to provide the scales and grade indicia in the form of verticalcolumns that they may be shaped to'resemble a thermometer, and stillfother objects `reside to the divisions in which theJ grade-indicating in details of construction and Vnovel arrangements of parts as will bebrought out inthe course of the following description.` y

In the accompanying drawings in which like characters of reference designate correchart showing a modified method of fastening the sheet-members of thechart together; F1gure`6, an enlarged section on the line 6-6, Figure 5; and f v Figure 7, a. fragmentary face view of a A chart of modified form.

In the drawings, the reference numeral 5 designates the backY member of the chart and 6 the face member of the same. `Both members are preferably made of paper, and the l back member isusuallyL heavier than the other toA chart.

color ofthe face memberasclearly indicated in the drawings as at 7. Y

`The two sheets of paper as shown in Figure 1,` are fastened together by sewing or stitching in a manner hereinafter to be more n fully described. j j The 4face member is graduated by .horizontal lines 8 and vertical lines 9, the vertical ruling being divided into columns by heavier lines 10. Between eachtwo horizontal Ylilies vis a removable strip 12 defined by'twofparallel perforated or otherwiseweakened lines and the chart" has an alinement with fthese strips oblong windows 13 forthe 'insertion of the names of subjects, individuals, teams, shifts, or other matter, the progress or ad# vance of which isto be indicated'on the graduated scale.

The names are printed or typewritten on a strip of paper 14 which is `fastened-upon give the required rigidity to the Theupper surface of the back memberis of `a distinctive color contrasting .with the in'o the back ot the lower sheet by a suitable adhesive or other means so that it is readily removed or replaced, it being understood that the names are properly spaced so that they will register with the windows as indicated in Figure 1.

Above the columns and cooperative 'therewith are tiers of cumulative alphabetical designations 15 which designate the values of the different graduations. Inasmuch as the designations are not a part of the present invention and their use has been fully explained in the original application, no turther description is necessary.

The sewing or stitching by which the two sheets are fastened together is preferably applied in lineslG along the edges of the chart and in lines 17V coincident with the horizontal lines between the removable strips. The lines of stitches may be made by means et an ordinary sewing machine orr on a machine constructed especially for the purpose.

In the use of the chart, the strips 12 are torn awayin accordance with the progress made by the person or in the subject designated in the space at the end et the strip, the exposed portion et the tace of the back member clearly indicating'by its contrasting color, the degree of said progress, by cooperationl with the scale on the tace member.

The stitchings by which the two-sheets are fastened together permit o t Vthe ready removal ot any part ot the strips without tearing or disturbing other parts of the tace sheet.`

The chart may be used tor commercial records such as those of salesmen in an industrial concern, and tor other purposes of similar nature, but it is particularly adapted for school work to separately indicate the progress ofv a number ot pupils in one subject or lof, one pupil in a number of different subject-s.

In the form illustrated in Figure 7 the detachable strips'18 are arranged vertically o-n the sheet between parallel lines represented 'by lines of stitches 19, as before, the graduated 4scale is formed `by equidistant cross stripes 2() between thelines, and degree indications 21 outside the same. p y

' In order to render the chartmore attractive andto impress the significance of the same more clearly upon the minds of the pupils and other interested persons, circular portions of the tace sheet are cut away at the lower ends of the columns formed by the vertical -lines, to expose the contrasting surface of .the back member in the form of bulbs 22. It'y will be lobserved that the columns thus formed, simulatei thermometers oit conventional construction and that the portions of the surface olf the back member, expo-sed by the removal of parts of the detachable strips represent in connection with the circular eX- 4posed portions at'theY lower ends of the columns, the rising mercury of the thermometers.

In Figures 5 and 6 has been illustrated the method of fastening the sheets of the chart together by means ot staples 23 applied along the lines at opposite sides of the detachable strips or along the marginal lines ot the chart. The staples may be spaced farther apart that the stitches of the lines of sewing and they may be applied by any et Ithe stapling machines at present in use.

It is to be understood that the staples are the full equivalent of the sewing and that both methods of fastening the sheets together Vhave been included in the above description and in the hereunto appended claims by the general terms stitched,7 stitching7 or stitches, y

Having thus described my invention what I claim and desire to secure by Letters Patentis:

1. A chart composed et a back member and a face member fastened together, the tace member having removable strips to expose corresponding portions ot the surface of the back member, and the chart having windows alined with the respective-strips, and a member back ot the chart, bearing names registering with the respective windows.

2. A chart comprising a back member and a tace member fastened together by stitches in substantially parallel lines, the tace member having weakened lines between said parallel lines whereby to provide detachable strips.

3. A chart comprising a back member, a tace member fastened to the back member and having weakened lines between the fastening means, the .members being apertured to provide a window, and a sheet bearing indicia disposed to be seen through the window.

. 4. A chart comprising a back member, and a face member fastenedto the back member and having removable strips to expose the `back member, the members having registering apertures eonjointly providing windows related to the strips, and a sheet bearing indicia disposed to be seen through the window.

5. A chart comprising a back member and a tace member stitched together in parallel lines, the tace member having weakened lines between the lines of stitching to provide removable strips.

6. A chart of the character described, comprising a top member having a graduated tace, and a back-member having a face contrasting with that ot the top-member, the two members being stitched together with their said faces uppermost, and the top-member having a removable strip to expose the face of the back member, whereby to indicate degrecs oit progress by means ot the graduations on the tace of the top-member.

' 7. A chart of the character described, comprising a top-member having a graduated face, and a back-member having a face co1- ored in contrast with that of the top-member, the two members being stitched together with their said faces uppermost,and the top-member having a removable strip to expose the face of the back member, whereby to indicate degrees of progress by means of the graduations on the face of the top-member.

8. A chart of the character described, comprising a top-member having a graduated face, a back member having a face distinctive in appearance from that of the top-member, the two members being stitched together with their said faces uppermost, and the top-member having a portion removable by a tearing action to expose the face of the back member whereby to indicate degrees of progress by means of the graduations on the face of the top-member.

In testimony whereof I have aiiixed my` signature.
